Examples of java.rmi.server.UID

java.rmi.server.UID
A UID represents an identifier that is unique over time with respect to the host it is generated on, or one of 2¹⁶ "well-known" identifiers.
The {@link #UID()} constructor can be used to generate anidentifier that is unique over time with respect to the host it is generated on. The {@link #UID(short)} constructor can be used tocreate one of 2¹⁶ well-known identifiers.
A UID instance contains three primitive values:
- unique, an int that uniquely identifies the VM that this UID was generated in, with respect to its host and at the time represented by the time value (an example implementation of the unique value would be a process identifier), or zero for a well-known UID
- time, a long equal to a time (as returned by {@link System#currentTimeMillis()}) at which the VM that this UID was generated in was alive, or zero for a well-known UID
- count, a short to distinguish UIDs generated in the same VM with the same time value
An independently generated UID instance is unique over time with respect to the host it is generated on as long as the host requires more than one millisecond to reboot and its system clock is never set backward. A globally unique identifier can be constructed by pairing a UID instance with a unique host identifier, such as an IP address. @author Ann Wollrath @author Peter Jones @version 1.24, 06/02/23 @since JDK1.1
